To all whom z't'may concern: l

Be it known that'I, WILLIAM N. SHAN-v NoN, ,a citizen of the United States, and. a resident ofthe city of Brooklyn,

State of New York,`have invented a new land useful Improvementin4 Automobile-B Frame Extensions, of which the following .10i .has particular reference to the. meanszfor "transforming an ordinary pleasure vehicle l of standard type into a commercial vehicle v 'with an'extended frame or chassis.

's-a full, clear, and exact description; y This invention relates to automobiles and Among the objects-of theinvention therefreis to provide improved facilitiesuof a simple, reliable and easily-manipulated nature adapted to extend a standard automo# bile frame so as to support' a longer body instead of an vordinary .short body, for commercialpurposes.

l "ment and combination of parts hereinafter I I reference Vthe accompanying drawings,

With the foregoing and other objects in view. vthe invention ,consists in the arrangedesc'ribed and claimed, and while theinven- 4tion is not restricted to the exact details of construction'disclosed or suggested herein,

still for the purpose of illustrating a practical embodiment thereof reference is' had to in which like characters designate the same parts in' the several views, and in which-T' 1 Figurel is a. plan view of the principal parts of an automobile chassis withy my irnprovement incorporated therein, the .improved parts being shownl in 'heavy lines `While the standard or' oldparts are',shown las in light lines. Y

standard .bar '16 .which spring 25 when it is removed from the bar 4 isa horizontal sectional detail on the line drawings I` show' an engine l0 supported .upon a frame including side bars 11 and 12 and adapted to be connected through a rod o r shaft 13 with the differential '14 of the rear axle 15 supporting ordinarily a crossbar 16 -secured rigidly andpermvanently to the rear ends of, the'side ybars 11 an'd 12.-, Y

In the Wellknown type of automobile the jcrossbarf16 is secured to the rear endsyof the side bars 11 and l2 by nmeansv including a pair of corner brackets '17' land 18 each connected *to its side bar by rivets 19 or their equivalent, extending through the upper iange'of such bar, and a rivet 20er its equivalent, @passing laterally through `the main web of the side bar. Each of these brackets furthermore is secured to the ad.

'acent portion of the crossbar 16 by means of a permanent rivet 2 1 or its equivalent, the axis of the rivet being. longitudinal of Athe machine. The upper Harige of each side bar is extended rearwardly as indicated at 22 to overlie the top of the crossbar While the lower flange is similarly projected be neath' the crossbar as indicated at 23. A A ver tical1 fastener 24- passes through both of these;

bar extensions and the crossbar. This crossbar 16 of arched channel construction and is calculated to receive the upper portion of the 'rear spring 25, the ends of the crossbar projecting laterally beyond theside bars 11 and`12.

In carrying out my invention in a practical form Iemploy an auxilia' constituting a substantial duplication of the will receive the crossbar 26 16 .and assembled'in its rearwardly extended l the. front to-fit exactly over the'tapered rear lend of vthe adjacent standard'bar, the up..

Each of these lex` proper comprises side vided With a hole '34 t0 per flange of the extension bar being provided with "a series of swells or convexitiesv 29 to take -over the heads of the rivets 19 and 24 Without-obstruction, and the lower liange is provided .Withv a downward com vexity or swell 30 to take over the lower end of the rivet 24 sothat. the rear end of the .standard`side bar is snugly embraced by the flaring frontend of lts extension bar.

The web portion of the extension is provided with a cut-out or hole Bli'ormed by striking out a lip 32 at rightangles to the main portion ofv the web. y This hole allows the extension bar to take directly over the outer free end of the crossbar 16 so` that the lip 32 will lie squarely against the rear face of the bar 16- to which it is fastened byv means of a rivet 33 or its equivalent./ InA front of the proiecting end of'the crossbar 1'6 the web of the extension bar may be proaccommodate the head of the fastener 20.

'The rear end of each extension Abai' is strongly secured to the adjacent end of the auxiliary bar 26 by means including'V a lip 35 bent'- outwardly from therear endof the web and fastened to the front flange of the bar 26 by means of a rivetfBI The top flange of the same extension bar is thus adapted to lie uponth'e top of the auxiliary bar as indicated at'LB'? where it is fastened by a fastener 38. 1

This rear by two extension bars 27 and 28 and the crossbars l'and 26, which is Asubstantially rectangular in plan, has ea'ch cornerthereof braced in a peculiarly strong manner by i means of a novel form 'of corner bracket degio .signed by 4me and comprising an endless device includinga rightangularportion 39 andan arc-shape` l connection 40` opposite i the rightangle.

" The rightangular portion of-each bracket is fitted squarely against one 'I of the vertical flanges ofa crossbar bv fasteners 41 and upon .the inner faceV of the web portion of wthe 'side bar extension by means of fasteners 42. ,The outward or convex forni of the connection .40 `adapts itself to accommodate the introduction of 5b' these several fasteners.

With the frame constructed as indicated i 'the adaptation of the driving connections thereto isl comparatively simplel Referring rear endv by a hanger bar 46 having .its ends l to-the' side bars 1l and 12 by U-v bolts 47 and 48 respectively.. The rear.

' I now to Figs` .secured 1 .and 2 it will be appreciated that in order to employthe same shaft 13 and in practically the same relation to the differential and the driving device is in its original position, I provide a rearwardly 'i extending horizontal 'shaft easingl adapted to house a short section of tie shaft 44 to make connection With the. universal. joint at45. lThe casing 43 is supported at its is embraced by portion of the 'frame-comprised crossbar,

hemispherical socket piece 49 of the 'casing a stirrup 50 extending outwardly through the hanger bar. The channel members 11 and 12 U-bolts 475 and 48 may be provided with filler blocks '.151 made of wood or the like to increase the stability of this part of the.

at the region of the '-structure. The same is true also at 52 where the flaring front ends of the extension bars embrace the rear ends of the standvardside bars 1-1 and 12, these latter blocks 52 being secured by .vertical bolts-53 which pass through the horizontal. angeportious ofthe overlapping bars.

In' an automobile frameextension, the combination with a standardl frame comprising parallel side b ars and a crossbar rigidly and permanently connected thereto, the rear ends'of theside bars being tapered and the t'rossbar having its ends extending heyond the sidebars, of a pair of extension bars having holes formed therethrough to .'receive the projecting "ends of the .crossbar and having the end portions thereof in front of the holes flared and embracing the tapered portions of the first mentioned bars, and means to-rigidly secure the extension bars to the crossba'r andthe rear ends of the first mentioned bars. 1
